Figure 43 Area detection tool example
The Area detector operates by comparing the normalized ECoG area (area per second) in a short-
term trend window (typically 1 to 4 seconds) to the normalized ECoG area in a long-term trend
window (typically 1 to 2 minutes). Detection occurs when the difference between the short-term and
long-term trend windows exceeds a programmed threshold (typically 37.5% to 100%).
